In the recent years, studying Bohr inequalities become an interesting topic of research for the functions of one as well as several complex variables. The notion of Bohr inequality has been generalized to several complex variables (see [1]}, [2]}, [3]}, [4]}), to planner harmonic mappings (see [5]}, [6]}, [7]}) to polynomials (see [8]}), to the solutions of elliptic partial differential equations (see [9]}, [10]}), to elliptic equations (see [11]}), to vector valued functions and operaotor valued functions (see [12]}, [13]}), to analytic functions in norm linear spaces (see [14]}) and in a more abstract setting (see [15]}). In 1977, Boas and Khavinshon [3]} extended the Bohr inequality to several complex varibales by finding multidimensional Bohr radius. Bohr's theorem attracted a greater interest after it was used by Dixon [17]} in 1995 to characterize Banach algebras that satisfy von Neumann inequality. The generalization of Bohr's theorem become now-a-days an active topic of research. In 2001, Aizenberg et al. [2]}, and in 2013 Aytuna and Djakov [19]} studied the Bohr property of holomorphic functions while Paulsen et al.
[20]} extended the Bohr inequality to Banach algebra. The relevance between Banach theory and Bohr's theorem was explored in [21]}, [22]}, [17]}.
